Kiss Me Kiss is an original song from Sega's ONGEKI rhythm game, composed and arranged by Takuya Ohata and performed by the in-game unit bitter flavor, a duo pairing Haruna Sakurai (voiced by Reina Kondo) and Ayaka Saotome (voiced by Yui Nakajima). The track arrived in maimai DX Splash PLUS as part of the ongoing cross-series collaboration linking ONGEKI, CHUNITHM, and maimai, bringing its bright pop-rock sound into the maimai song library at a steady 140 BPM. Lyrically, the song plays with flirtatious tension and coy romantic pursuit, each vocalist's distinct personality bouncing off the other, Sakurai's earnest teasing countered by Saotome's more knowing delivery, a dynamic that carries through both the game-size version and the extended mix on the ONGEKI Vocal Collection 03 soundtrack. The maimai port features charts across all five DX difficulties, with the Master chart (level 12+, constant 12.8) designed by Jack and the Expert chart (level 9+, constant 9.6) by はっぴー, offering players a fairly dense note layout that leans into the song's driving beat and pop energy.
